<body onload="setInterval('document.all.time1.innerHTML=new Date().toLocaleString()',1000)">
<span id=time1></span> |
|
|
|
此方法只能显示客户端的系统时间
var thisDay = new Date(); var year = thisDay.getYear()+1900;//年 var month = thisDay.getMonth()+1;//月 var date = thisDay.getDate();//日期 var day = thisDay.getDay();//星期0-6 |

在jsp中还可以使用date 和 GregorianCalendar两个类

给个思路--实时显示服务器端的时间：
在页面上放个 iFrame，在里面打开一个 asp 文件，显示服务器时间，并让该页面不断自动刷新 -- 就像老式的聊天室页面刷新。 --- 就 OK 了. |
